The A 7Z47MPSN15M is a self-aligning, press-fit needle roller bearing with a 15 mm bore, designed for high-speed, high-load applications without requiring precision holes in the housing. The bearing features a drawn cup with a carbon steel housing and black oxide finish, operating between -30°C and +100°C. It requires a shaft material hardened to HRC 58-64 with a surface finish of 0.4 µm or finer. The housing panel hole diameter is 31.8 mm, and the maximum radial load rating is 7800 N at a maximum speed of 16,000 rpm. It self-aligns to ±5° and is installed by press fitting, with the insert protruding and the punch relieved to accommodate it.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
